Title: Pickup
Inventor: YOSHIDA SHINYA
IPC: G11B7/135
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a pickup which is capable of dealing with a recording medium increased in recording capacity (recording density) and is made smaller in size than the conventional device. SOLUTION: The pickup has a light source 1, a beam splitter 2, a photodiode 3 for light output monitor, a collimator lens 4, an objective lens 5, a polarized light separating element 7 and a photodetector 8 and irradiates the surface of a recording medium 10 with near UV light (light of a near UV region). The polarized light separating element 7 is disposed on an optical path from the recording medium 10 to the photodetector 8. The polarized light separating element 7 consists of a Wollaston prism composed of a pair of members disposed in such a manner that their optical axes intersect orthogonally with each other. A pair of these members are composed of Li2B4O7. The Li2B4O7 allows the sufficient transmission of the near UV light and has a double refractivity much higher than that of SiO2.  The Li2B4O7 is therefore adequate as the optical parts of an optical system using the light source to emit the near UV light.

Title: Image forming device
Inventor: MUNAKATA ATSUSHI
IPC: G03G21/14
Filed: 2000-05-31
Abstract: PROBLEM TO BE SOLVED: To allow the start of image formation even before the detection of the home position of a transfer belt or intermediate transfer belt and to shorten the time from the start of the device to an output of a first image. SOLUTION: The image forming device has a transfer belt 8 which is rotated by an ultrasonic motor 5 via a drive roller 12. A marking 22 is provided on one area of the periphery of the belt. The marking 22 is detected by a sensor 23 to detect the home position of the belt. While the belt makes one rotation after the sensor detects the marking at a certain point in time, pulses of an encoder, which is incorporated in a motor 5, are counted. The phase of the belt in the direction of the rotation is thereby detected. When the marking is detected again, the pulse counter is reset for the subsequent counting. The phase of the belt, at a point in time that the image forming operation is finished, is stored in a storage means. Holding a grasp of the phase allows the start of the subsequent image formation even before the passage of the marking through the sensor.
